Function and system design
Measuring principle
Example of an application of the field display unit
The display unit records an analog measuring signal and shows this on the display with background
illumination. The LC display shows the current measured value digitally and as a bargraph with limit value
violation signalling. The display unit is looped into the 4 to 20 mA circuit and obtains the required energy from
there.
Measuring system
Microcontroller controlled display unit in single chamber field housing with illuminated LC display. The
measuring range, decimal point and offset of the display can be configured comfortably by means of three keys
in the device with the housing open or by means of a PC with the ReadWin® 2000 PC software. The
background illumination of the display is always activated and does not require additional wiring for the power
supply.
Input
Measured variable
Current
Measuring range
4 to 20 mA (reverse polarity protection)
Input
• Line voltage drop < 4 V at 3 - 22 mA
• Max. line voltage drop < 6 V at max. short-circuit current 200 mA
Output
Output
Digital limit switch
Passive, open collector:
Imax = 200 mA
Umax= 35 V
Ulow/max = < 2 V at 200 mA
Max. reaction time to limit value = 250 ms
Signal on alarm
No measured value visible on the LC display, no background illumination.
Transmission behavior
The display unit allows the HART® transmission protocol to pass unimpeded.
